Dr. Jones was very concerned about my subscapularis muscle that he reattached breaking loose. From my years of not using my shoulder properly, the muscle had severely shortened and was extremely tight when he reattached it. So that was part of the reason he spoke so strongly about the sling.
But, on the day he released me, he told me I could leave it off during the day if I was where I could support my arm somewhat. That was pure heaven! So, from day one when I got home I didn't wear the sling at all during the day until I went to bed at night. I didn't need or take naps during the day or I probably would have worn it then. I didn't need a lot of icing as I had virtually no pain or swelling in my shoulder or arm. I consider myself very lucky about that.
If you have swelling, be sure and ice a lot for it. If you have any pain, take your meds on a set schedule as that will help keep inflammation down and reduce swelling. Go easy on any exercises as long as you're swollen BUT be sure you do at least passive pulley exercises twice a day to keep the shoulder loose.
If you have a question about the permitted movements, contact Dr. Jones's office. My instructions were different because I had that muscle problem. He or his nurse will know your case. You may be permitted more motion than I was. Obviously you shouldn't do anything that causes pain, though.
